The only Zappa I'd considering adding to my collection (at this time), would be something by that BWS band, with the Bunk Gardner, Ian Underwood, Don Preston, etc. Is there anything from that lineup coming out? Or am I good with BWS & Weasels, Hot Rats in addition? I bought most of the Verves in real-ish time (in print, in stores) and of course am keeping that. But not adding to.
FWIW, I really liked the Flo & Eddie stuff when it got all operatic and shit, Billy The Mountain was a freaking epic. But the whole Mud Shark thing hasn't worn well with me, as has not Zappa's ongoing puerile genital humor (c.f. Roy Estrada, #youfuckingasshole). I've learned to take the great with the cringeworthy, but have no desire to add any more.
